One Pentagon email exchange with Ben Rhodes, a senior White House national security aide, said Boal had been briefed by CIA officials "with the full knowledge and full approval/support" of Leon Panetta, who served as CIA director and then Secretary of Defense while the film was being prepared.

A second person familiar with the matter said the committee had acquired copies of the CIA records last year.

The committee originally obtained the uncensored records at the request of Republicans, who were looking for evidence that intelligence or Pentagon personnel inappropriately shared classified information with the filmmakers, this source said.

Other Congressional Republicans, most notably Representative Peter King, outgoing chairman of the House Committee on Homeland Security, complained loudly about dealings between the Obama administration and the filmmakers following reports it would be released shortly before the 2012 Presidential election. Ultimately, the film was not released until after the election.

Two days after the Senators made public their letter to Sony, the CIA released a statement by Morell, who said that Zero Dark Thirty was a "dramatization, not a realistic portrayal of the facts," and that while the agency had "interacted" with the filmmakers, it did not "control the final product."

Morell's statement was equivocal on whether "enhanced interrogations" had produced information critical to finding bin Laden.

"Whether enhanced interrogation techniques were the only timely and effective way to obtain information from those detainees, as the film suggests, is a matter of debate that cannot and never will be definitively resolved," Morell added.
